My surface tablet is shared with a friend. She uses a separate account, with admin rights.
Being an admin, she is able to gain access to all my files. Even my OneDrive files.
I guess I could follow these steps to prevent this (it basically states that you'll need to disable access for the targeted administrator), but the same scenario would be present if I were to create another administrator account.
You could say "don't make her administrator", but I don't want to mess with her personal files as well.
Somehow this feels as a security flaw... or am I mistaken?
Is there any way to protect private files from "administrator eyes" by default?
